Abstract

In this paper we examine the heat transfer characteristics of three-dimensional rotating flow of convective hybrid nanofluid flow over a stretching/shrinking permeable sheet in the presence of a magnetic field and heat source effects. Hybrid nanofluids exhibit promising characteristics for various applications, particularly in enhancing heat transfer rates. The hybrid nanofluid used in the paper is alumina (Al2O3) and copper (Cu) with water (H2O) serving as the base fluid. The governing nonlinear partial differential equations are transformed into linear ordinary differential equations using similarity transformations and are numerically solved using the bvp4c function in MATLAB® software. The influence of various governing parameters on the velocities and temperature profiles is represented through graphs. The parameters include magnetic field, Darcy permeability, Eckert number, suction effects, Biot number, rotating parameter, and heat source parameter. Further, the impact of suction parameter on the skin friction and reduced heat transfer is also examined.
